Susceptibility near a critical point. Consider a ferromagnetic system withn spins per volume,where each spin has magnetic moment u. There is an effective B-field from the meanmagnetization, BĘ = AM. However, now there is an external field, Bo, such that the total effectivefield is B = AM + Bo.(a) Assume Bo = 0 (no external field). Near the critical point, the magnetization will have theform M c |t- tel. Calculate t, and ß.(b) The magnetic susceptibility x = dM/dB near the critical point will obey x x (t -T)".When t > T, M and Bare both very small, so x = M/B also works. Calculate y.(c) Sketch or plot M from part (a) and x from part (b) on the same axes, both as afunction of t/t.. Make sure you only plot x for t/t, > 1.

here we are talking about ferromagnetic material and we need to find magnetization and…

You have a square loop with each side of length 'a' and a circular loop with radius 'a'. Both of these loops lie in the x-y-plane, where there is a uniform magnetic field B pointing at some angle 0 with respect to the positive z-direction. Each loop has the same number of coils and carries the same current, in the same direction. Therefore, the ratio of magnetic moments (u) in the loops, [square] / [circular] = O 1/ T O T 14 O 4/ T
